Sharks 'functionally extinct' in Mediterraneanhttp://apocadocs.com/s.pl?1213276380
Researchers used fishermens' notes and archives to show that numbers had declined by as much as 99 per cent in the last two centuries.... The scientists who conducted the study said that 47 species of sharks live in the Mediterranean, but that many of them had not been seen for decades.
They added that other predators, such as whales, turtles and large fish such as tuna, "had declined similarly" and that the entire ecosystem of the Mediterranean was at risk. Sharks help control the populations of various fish and keep the food chain balanced.
